Injuries to first-choice Jose Reina has meant the Australian has featured 15 times for the first team - having played just four times in two previous seasons - and started the last two league matches.
"To have had 15 appearances is probably more than I would have thought I'd get at the start of the season," he told liverpoolfc.com.
"I feel as though in the majority, I have performed fairly well, so I'm happy.
"Obviously circumstances dictate when I am going to get those games but I am more than happy to have had those games.
"I wouldn't mind a few more but I think it's been a decent season all in all."
